Architecting a Secure Landing Zone in EUSC
🔒 This post explains how to design a secure, scalable landing zone for the AWS European Sovereign Cloud (aws-eusc), a partitioned AWS environment operated within the EU. It covers account structure and governance, identity as IaC, centralized logging to a SIEM, data protection, perimeter and network design, CI/CD and artifact distribution, and incident response. The guidance maps to the AWS Security Reference Architecture and the AWS Well-Architected Framework, and highlights which behaviors are partition boundaries versus configurable choices.
